When a cryptic stranger warns Annette that she is in danger of being murdered -- just like her sister -- by an ancient evil that dwells between dreams and reality, Annette initially dismisses the idea until she is attacked in her sleep by an unseen entity. Annette soon learns what she experienced is known throughout history as Old Hag Syndrome, a horrifying affliction that causes victims to awake, paralyzed, unable to scream while they are tormented by hallucinations.
